WILLIAM LYON, OF BURLINGTON, IOW'A.

MACHINE FOR SWAGING AND JOINTING SAWS.

SPECIFICATION forming part of Letters Patent No. 321,376, dated June 30, 1885.

Application filed April 5, 1884. (No model.)

1'0 aZZ whom it may concern:

Be it known that I, WILLIAM LYON, a citizen of the United States, residing at Burlington, Des Moines county, State of Iowa, have invented a new and useful Saw Swaging and J ointing Machine, of which the following is a specification.

My invention relates to improvements in saw swaging and jointing machines; and the objects of my improvements are, first, to provide a movable anvil for swaging the teeth of rotary saws to the required width for clearance, and, second, to provide for the proper adjustment of an emery-wheel to a rotating saw, for the jointing of its teeth to the proper length and width. I attain these objects by the mechanism illustrated in the accompanying drawings.

Figure 1 is a side view of the device; Fig. 2, a top view; Fig. 3, an end view; Fig. 4, a perspective view looking across the frame toward the saw; Fig. 5, a perspective view from the other side.

In the annexed drawings, the letter A represents the frame of the machine, a a being the ends, and b I) the brace-beams, the last having the boxing c c.

G is a shaft journaled in boxing c c, and having pulleys (Z d and bevel-wheel 6. Beam Zr has boxes 6 e, in which rotates shaft f, having bevel-wheel f, which forms a bevel-gear with wheel 0. To shaft f is keyed the pulley Attached to frame A are the boxes h h the former a sliding box and the latter holding a rotative pulley, 2', which is connected by a belt with pulley 5 Through the boxes h and h and pulley 2' passes a shaft, K, having a keyway to engage a lug in said pulley, so that the shaft rotates with the pulley, and is also movable lengthwise independent of the latter. On shaft K is keyed a worm gear, E, which engages a worn1-whee1, a, on a shaft, a, which turns in boxes mm, secured to a frame, D, arranged transverse the frame A, and to slide lengthwise the latter by means of a screw-shaft, p, which engages threaded perforations 1-1- in the ends of frame A, and another, 0, in frame D. Gears land a are thrown in and out of engagement by raising and lowering box it, which is held by set-screw h Through the end a; of frame A passes the shaft E, working in journals, to which shaft the arm F is keyed, so as to admit of being tilted backward and forward. To arm F is fastened the die G, which is of proper shape to receive the tooth to be swaged.

H is a support, preferably of the form shown, sliding in dovetailed grooves upon frame A, and moved by shaft L, working in a threaded perforation in the frame Aand in the support.

The frame M slides in dovetailed grooves in end :0 of the frame A, and is provided with a threaded perforation, in which engages a shaft, N.

Upon the frame M is pivoted at z a small frame, 0, composed of a horizontal base-piece and two uprights, in which is journaled a shaft, 3 on which are keyed an emery-wheel, P, and a pulley, Q, the latter connected by a belt with pulley d. Pulley d is connected by belting with the motive power. Frame A also has the stays R and R, for keeping the saw steady. Stay R consists of an arm, '2', held in a slide, r,which is adjustable by wheel 2' along the frame A. This bears against one side of the saw. Stay R is pivoted to the frame A at the lower part, and consists of an arm, r carrying a pin, a", which supports the opposite side of the saw.

The device operates thus: Arm F is tilted backward and support H moved forward to ward sliding frame D, and there is fastened, by means of screw and collar or otherwise, the saw to be swaged upon shaft a. Frame D is moved toward arm F, according to the size of the saw to be swaged, arm F is brought forward, die G coming between the saw-teeth, and support H is moved backward until arm F rests on it. The teeth are then in position to be swaged, the arm F, die G, and support H forming an anvil. The teeth being swaged, frame D is moved from the anvil toward the frame M, and by moving the sliding box it the gears a and Z are connected and the saw revolved. The emery-wheel is then turned, the saw being against it and adjusted thus: For making the teeth of uniform length, the emery-wheel is slid by shaft N in front of the saw, where it may be moved across it by moving frame M, so as to avoid grooving the wheel. To dress the sides of the teeth, the wheel is 7 moved to the sides of the saw, and the shape of the tooth is retained by allowing the frame 0 to turn on its pivot.

What I claim, and desire to secure by Letters Patent, is

1. In a saw-swaging machine, the combination of a frame, a horizontal adjustable shaft or arbor, a horizontally-adjustable rest, and a die secured to an arm pivoted to the frame, as

gear n, aworm-gear, l, shaftK, provided with a keyway, and a pulley, t, provided with a lug, substantially as and for the purpose herein set forth.

5. The improvement in the means of swaging and jointing circular saws which consists in the combination of the bolted and tilted arm F, to hold die G, and the sliding support H, in combination with the pivoted frame 0, carrying a shaft, 3 with emery-wheel P and pulley Q, connected with pulley i by belt, and the sliding frame M, moved by worm-shaft N, substantially as and for the purpose herein described.

WILLIAM LYON.
